[RESOLVED] IP filtering

kemu_

Does any1 have any good ideas how to filter ip's with a php page. What i mean i have a range of ip's and some individual ips, and i would like to have the php decide if he allows something to be done comparing it to persons ip...

You can find the IP the request is originating from (or at least that of the proxy forwarding the request) in $_SERVER['REMOTE_ADDR']. Compare that with the IPs in your list.

yes i knew that, but what i meant was that how to DO that comparison? eg. if i have a range of addresses 192.168.0.0 - 192.168.0.254 and the users addr is 192.168.0.128, how do i do the actual comparison?

There are all sorts of comparison methods you could use. One is to use [man]ip2long[/man] to convert all three IPs into a number and then see if the user's IP is between the other two.
